Накратко на български

Масиви от неутрални атоми се използват за симулиране на взаимодействия между частици, като например поведението на кварки и глюони. Това помага за изследване на фундаментални физични явления, които са недостъпни за традиционните компютри.

PROgramming Gauge-invariant Rydberg AtoM arrays

The simulation of quantum systems is one of the most promising near-term applications of quantum technologies. In particular, lattice gauge theories (LGTs), which underpin the Standard Model of particle physics, describe a vast range of strongly interacting phenomena, from the behaviour of quarks and gluons in high-energy physics to exotic states of matter in condensed matter systems. However, many important questions in this field remain unanswered, as they are beyond the reach of classical computational methods. PROGRAM (PROgramming Gauge-invariant Rydberg AtoM arrays) addresses this challenge by developing new quantum simulation strategies for lattice gauge theories using arrays of neutral atoms. These platforms are among the most advanced quantum technologies available today, capable of controlling hundreds of atoms with high precision. The goal is to design protocols that fully exploit the capabilities of these devices to explore complex gauge-theoretic phenomena that are currently inaccessible. The project focuses on two major research objectives: 1) Scaling gauge-matter interactions beyond one-dimensional systems using analog simulators, and develop protocols to simulate relevant non-equilibrium phenomena driven by these interactions. 2) Develop hardware-efficient digital quantum simulation protocols that account for non-abelian gauge fields as well as fermionic matter, co-designed for qudit and fermionic architectures, respectively. By advancing these goals, PROGRAM aims to establish practical quantum simulation protocols that can be implemented in current and near-term devices, ultimately contributing to the long-term vision of quantum technologies delivering insights into fundamental physics.

Цел на проекта

Many strongly-correlated phenomena in condensed-matter and high-energy physics, from high-Tc superconductivity to quark confinement, can be described by lattice gauge theories (LGT), field theories invariant under local transformations. The immense computational complexity associated with solving LGT using classical computers hinders progress in these fields, where many questions remain open. Although quantum computers can address these questions more efficiently than classical devices, current quantum hardware is limited in the absence of error correction, complicating the reach of a practical quantum advantage in the near term.Co-designing both quantum hardware and software tailored to simulate LGT, addressing non-trivial regimes while minimizing experimental resources, is therefore a challenging but timely task. Rydberg atoms in tweezer arrays, which have recently emerged as a powerful quantum simulation platform, offer unique capabilities that can be harnessed in this direction. On the one hand, the strong Rydberg interaction and the associated blockade mechanism naturally leads to emergent local symmetries. On the other hand, the possibility of controlling many internal atomic states as well as using fermionic atoms allows to locally encode and simulate non-abelian gauge fields and fermionic matter fields, respectively, minimizing resource overheads.PROGRAM will investigate this hardware-efficient approach and develop quantum simulation protocols for LGT using Rydberg atom arrays, focusing on three main challenges: (i) simulating non-equilibrium LGT dynamics in 2D, and (ii) implementing non-abelian gauge symmetries, as well as (iii) fermionic matter fields, in a scalable manner. The Researcher will design these protocols using both analog, digital and variational near-term resources, benchmark them in the presence of experimental errors, and run some of them using existing quantum hardware.
